Love calculator (just for fun)

For entertainment only: a love compatibility score from 0 to 100 made from two names. The same pair always gets the same score; it predicts nothing.

Worth a date

Romeo and Juliet score 54% — “Worth a date”. The number comes from a hash of the letters in the names, so it is the same every time and means nothing about a real relationship.

계산 방법 S

  1. Normalize the names

    Keep only letters, lowercase them and sort the pair so order doesn't matter: “juliet+romeo”.

  2. Hash

    32-bit FNV-1a of the UTF-8 bytes of “juliet+romeo” is 174137891.

  3. Scale to 0–100

    174137891 mod 101=54174137891 \bmod 101 = 54

Love calculator (just for fun) 소개

The score is a hash, not a measurement. The calculator keeps only the letters of both names, lowercases them, sorts the pair so the order doesn't matter, runs the 32-bit FNV-1a hash over the result and takes the remainder after dividing by 101, which gives a whole number from 0 to 100. The verdicts cover 0–20, 21–40, 41–60, 61–80 and 81–100.

The result is for entertainment only and does not predict anything about a real relationship. The same two names always get the same score, so Romeo and Juliet get 54% ("Worth a date") every time, in either order and any mix of capitals.

Every letter feeds the hash, so a nickname, a middle name or a surname gives an unrelated score.

자주 묻는 질문

How does this love calculator work?

It turns the letters of two names into a number with a fixed formula. The letters are lowercased, the two names are sorted into a pair, and the pair is hashed with 32-bit FNV-1a and reduced modulo 101 to a score from 0 to 100. Nothing about the people themselves goes in, so the score is entertainment and carries no meaning.

Can a love calculator predict a relationship?

No. The score comes from the spelling of two names and says nothing about compatibility. What does predict relationship quality is how each partner experiences the relationship: in a 2020 PNAS study pooling 43 longitudinal couples datasets from 29 laboratories, perceived partner commitment, appreciation, sexual satisfaction, perceived partner satisfaction and conflict were the top predictors, and relationship-specific measures explained up to 45% of the variance in relationship quality at the start of the studies.

Why do the same names always get the same score?

Because a hash is deterministic: the same input always gives the same output. The names are normalized first, so "Romeo" and "Juliet" or "juliet!" and " ROMEO " both become juliet+romeo and score 54. Adding a surname or using a nickname changes the letters and gives an unrelated score.

Do accented and non-Latin names work?

Yes. Any Unicode letter counts, including accented letters and non-Latin scripts, and the letters are hashed as UTF-8 bytes, so Zoë and Zoë score 71. Digits, spaces and punctuation are ignored, and a name with no letters at all gets an error.

“Love calculator (just for fun)”의 정확도는 어느 정도인가요?

정확도는 입력값과 계산 방법의 가정에 따라 달라집니다. 십진 연산은 유효숫자 50자리를 사용하지만, 추정값·수치해석 방법·원본 데이터의 정밀도는 더 낮을 수 있습니다. 표시값을 반올림해도 이러한 한계는 사라지지 않습니다. 독립적인 출처의 풀이와 대조한 계산 예시: 5. 예를 들어 “Romeo and Juliet”은 Python 3.8 FNV-1a of b'juliet+romeo' = 174137891; mod 101 = 54와 대조해 확인합니다.
